 the product of the magnetic permeability of a medium by the intensity of magnetic field in it — called also magnetic flux density
2.magnetic flux density is defined as the amount of magnetic flux in an area taken perpendicular to the magnetic flux direction. An example of magnetic flux density is a measurement taken in teslas.

2. magnetic flux density is defined as the force acting per unit current per unit length on a wire placed. it is a vector quantity and its unit is tesla.]]> 2018-08-06 08:46:21 UTC https://padlet.com/rajeswari_meganathan/i8bkbnf7oqh6/wish/272056644 aravindgokul19 https://padlet.com/rajeswari_meganathan/i8bkbnf7oqh6/wish/272056897  The process by which a substance, such as iron or steel, becomes magnetized by a magnetic flie. The induced magnetism is produced by the force of the field radiating from the poles of a magnet . 2. See magnitic flux density.
